Looks like the kid hasn't grown into his hand-me-downs yet, or for that fact grown a hat yet.
The guy in the middle hasn't grown into his either.
Ol' Rockefeller must of hit some hard times and had to deliver the oil himself!
This photo makes me think of an old family story. My paternal grandfather emigrated to the U.S.from Italy in 1913 at the age of 18. He made a beeline for San Francisco, CA where his two older brothers were. His first job was working with them building "the first" Standard Oil Co. tanker trucks.
At the time I was told this story it didn't occur to me (I was a kid) to get some details. I imagine they were building bodies on a running chassis, but have no clue what type of trucks they may have been. As far as I know there aren't any photos either, and everyone with any firsthand knowledge is long gone.
Thanks for another exceptional photo Jay!
Before there were tanker trucks there were tanker wagons. I have the remnants of one.
If you remember "Death Valley Days" starring Ronald Regan they were sponsored by Boraxo and they had the 20 mule team at the beginning of the show pulling the mine wagons and a tanker wagon.
